The awesome thing to understand once you know this type of information is that people are just people. Niggers aren't bad, they are just different. Not all white people are puzzle solving geniuses there's a shitload of retards out there. Not all Asians are hive minds. Our genetics give us our baseline ranges of advantages and disadvantages. Our cultural, ethnic, and homelike environments provide a great deal of individualized pressure on what we do within those ranges.

The problem we have as a society isn't hate and xenophobia, it's not allowing people to understand that not everyone can be a rocket scientist or a basketball player or a writer. That we should work towards understanding our limits, pushing ourselves to maximize our strengths and minimize our weaknesses, and allow us to acknowledge that genetic subspecies have always and will always work better in their own environments than in forced inclusive social structures. Day geckos and leopard geckos are both geckos, but they have evolved to be great at very different things. We need to stop trying to think any of us are simply better or worse, and realize we are better or worse at certain things because our evolution has given us those advantages and we should be celebrating and promoting them. I think we get wrapped up in their "emotional control" scheme on both sides. We don't have to hate to understand, and we don't need to wipe reality away to protect people's feelings.

Aww thanks. There are lots of intertwining and cultural pressures and sub species isolation as well, but those are more recent and less overall impact full as the big picture movements and breeding.
